Fig. 1 is please referred to, Fig. 1 is a kind of structural representation of the detection device of feeder ear wiring condition provided by the utility model
Figure.
The detection device includes PE line terminals, fire line terminal and zero terminal, the first diode D1, the second diode D2,
For isolation input and the first isolating device U1 and the second isolating device U2 of output, the first pull-up resistor R1, the second pull-up electricity

Fire line terminal is connect with the anode of the first diode D1, the cathode of the first diode D1 and the first isolating device U1's

Module 1 connects, and the ground terminal ground connection of the first isolating device U1, the second end of the first pull-up resistor R1 is connect with DC power supply, the
The output end of two isolating device U2 is connect with the first end of the second pull-up resistor R2, and common end is connect with identification module 1, and second
The ground terminal of isolating device U2 is grounded, and the second end of the second pull-up resistor R2 is connect with DC power supply；Identification module 1 is used for basis
In the simple two-way signal identification feeder ear of acquisition the case where each circuit.
Specifically, detection device provided by the present application can detect whether PE lines are effective, and whether PE lines are reversed with firewire, fire
Whether line and zero curve are reversed, and whether firewire is connected in PE line terminals.
If system wiring is normal (fire line terminal accesses firewire, and zero terminal accesses zero curve, and PE line terminals access PE lines)
And PE lines are effective, then when fire line terminal inputs positive half cycle voltage, have positive voltage difference on firewire and PE lines, to make first every
It is connected from device U1, the signal (first via signal) of the first end for the first pull-up resistor R1 that identification module 1 acquires is low level.
When fire line terminal inputs negative half period voltage, the first isolating device U1 can end, and the first via signal that identification module 1 acquires is height
Level, so the avatar for the first via signal that identification module 1 acquires is similar to square-wave signal.Due to electric between PE lines and zero curve
Pressure difference is small, so the second isolating device U2 is in cut-off state, and due to the presence of the second pull-up resistor R2, so identification module
The signal (second road signal) of the first end of second pull-up resistor R2 of 1 acquisition is high level.Therefore, when system wiring is normal and
When PE lines are effective, for first via signal similar to square-wave signal, second road signal is high level.
If system wiring is normal, but PE lines are invalid, then when fire line terminal inputs positive half cycle voltage, the first diode
D1, the input side of the first isolating device U1, the second diode D2, the second isolating device U2 input side can be formed into a loop.
At this point, the first isolating device U1 and the second isolating device U2 are both turned on, then first via signal is low level, second road signal is also
Low level.Conversely, when fire line terminal inputs negative half period voltage, the first isolating device U1 and the second isolating device U2 are turned off,
It is also high level that first via signal, which is high level, second road signal, at this time.As it can be seen that identification module 1 acquire first via signal and
The avatar of second road signal is similar to square-wave signal, and first via signal is identical with second road signal level, that is, is all height
Level is all low level.Therefore, when system wiring is normal but PE lines are invalid, first via signal and the equal class of second road signal
Like square-wave signal, and the level of first via signal and second road signal is identical.
If PE lines and firewire are reversed, zero curve connection is normal, then when PE line terminals input negative half period voltage, the first isolation
Device U1 conductings, first via signal are low level, and the second isolating device U2 cut-offs, second road signal is high level.When PE line ends
When son input positive half cycle voltage, the first isolating device U1 cut-offs, first via signal is high level, and the second isolating device U2 is connected,
Second road signal is low level.As it can be seen that the first via signal and the avatar of second road signal that identification module 1 acquires are similar
Square-wave signal, but first via signal and second road signal level, on the contrary, when i.e. first via signal is high level, second road signal is
When low level or first via signal are low level, second road signal is high level.Therefore, when PE lines and firewire are reversed, zero curve
When connecting normal, first via signal and second road signal are similar to square-wave signal, but the electricity of first via signal and second road signal
It is flat opposite.
If firewire and zero curve are reversed, the connection of PE lines is normal, at this time the voltage difference very little of fire line terminal and PE line terminals, the
One isolating device U1 is by first via signal is high level.When zero terminal accesses negative half period voltage, the second isolating device U2
Conducting, second road signal is low level；When zero terminal accesses positive half cycle voltage, the second isolating device U2 is by the second tunnel
Signal is high level, so the avatar for the second road signal that identification module 1 acquires is similar to square-wave signal.Therefore, work as firewire
Reversed with zero curve, when the connection of PE lines is normal, first via signal is high level, and second road signal is similar to square-wave signal.
If firewire is connected to fire line terminal and PE line terminals simultaneously, zero curve connection is normal, at this time fire line terminal and PE lines
The voltage difference very little of terminal, the first isolating device U1 is by first via signal is high level.When PE line terminals access positive half cycle electricity
When pressure, the second isolating device U2 conductings, second road signal is low level；When PE line terminals access negative half period voltage when, second every
From device U2 by second road signal is high level, so the similar side of the avatar for the second road signal that identification module 1 acquires
Wave signal.Therefore, when firewire is connected to PE line terminals, and zero curve connection is normal, first via signal is high level, second road signal
Similar square-wave signal.
As it can be seen that firewire and zero curve are reversed, PE lines connect normal and firewire while being connected to fire line terminal and PE line terminals, zero
Line connection is normal, and first via signal is identical with the avatar of second road signal, needs further to check circuit at this time, distinguishes tool
Body situation.

Zero terminal, the first diode, the second diode, for the first isolating device and the second isolator of isolation input and output
Part, the first pull-up resistor, the second pull-up resistor, DC power supply and identification module；Identification module is used to be believed according to the two-way of acquisition
